We recently upgraded both of our dogs walking gear! The dual length leash is perfect to tie up when you run into the store. The clip on the handle makes it so easy and convenient. When it is busy we have been using the short mode to keep our German Shepard by our side. Literally you get two two leads in one, a long and short option.
We got both the green and black leash and collars. The green is my favorite but the black is also fantastic. I know it wont ever show any stains , good for my dog Zac who is prone to getting dirty.
